>Using Watermelon rind for gardening

Can I use my empty watermelon rind to pot plants? more specifically potatoes? Or will it just rot and kill my precious tubers?

Judging by lots of the weird shorting comings in this house, I think the landlord bought it in poor condition and then did a lot of the repairs himself. I'm constantly coming across dumb things like electrical boxes not screwed into anything, or there's a screw but it is screwed into insulation. Most of the interior design elements were well done but the infrastructure parts are questionable. Everything screams "done over the weekend after watching a YouTube video". When the lease is up, I'll probably move.

they have to get rid of the chlorine somewhere.
when you make NaOH from salt you're left with tons of toxic chlorine. that's why Americans invented PVC-C with even more chlorine.

when it burns it creates hydrochloric acid and Dioxins and youre house is doomed after a cable fire or something.
they recently banned it for use in public buildings.

Ayo /diy I need some help,

I'm planning to build a small, amateur ROV at home using a 3d printer to design a pressure vessel and PVC for the main frame

I'll be printing using ABS, and the main pressure vessel will be a sphere to house a drone flight controller running inav, which is special drone firmware, and 3 cylindrical tubes for cameras, lights etc with a 30mm thick wall. The cylinder will also have between 30-40mm thick walls

The question is: how far will it go down? I'm estimating between 75-125m before anything catastrophic happens, but I happen to live quite far inland and the ocean is a 3 hour drive away, what's a good way to test the pressure vessels?

Also if any of y'all have any good advice would be happy to hear it

Think about the electrical penetrators you’re going to use to power and control this thing. I don’t want to discourage you from using PVC, but consider using black iron pipe. It’ll rust like crazy so you’d have to paint it. Bit it will be more rigid. You could even drill and tap black pipe to install a proper penetrator. The conductors for power and control may be the main danger of water infiltration into your device. The electrical penetrator could be pricy, but it could be the defining factor in how deep your device can dive.

I wouldn’t bother with mineral oil for your use. I think you’d struggle to keep your pressure vessels topped off. And you still have, a different set of, issues with preventing seawater infiltration.

I think you should strive for an operating depth of 10 meters. Maybe 15 or 20 meters is achievable. Unless you have access to real fabrication equipment, something is going to let go as you head for those depths.

what if he dips the electronics in epoxy?
>>
>>1825872

Just use standardized parts that have a pressure rating, this way you can go way deeper than your cable length probably lets you.

For example, high density polyethene pipes can easily have PN25 rating, that's 25 bars or 250 meters underwater, as pressure increases about 1 bar for each 10 meters of water.

And if you like metal, there's standards for PN250 which is 2500 meters, which requires 2500 meters of cable too.

Don't try to copy deep sea vessels or make 40 mm thick walls (jesus christ!) because it's not the hull integrity you need to worry about but plugging all the holes for the cables and making the thrusters waterproof instead.

Also, some tips:

>make it slighty positively buoyant so it comes up if it goes dark

>positive buoyancy lets you direct the flow from thrusters upwards so you won't mix the ocean/lake/whatever floor by trying to keep the ROV from sinking, blocking visibility with particles from the bottom of the lake/ocean

>if you like to adjust the buoyancy, you can make a ballast tank from a very large syringe

>some ROVs have tracks, it's not a completely crazy idea if you want to move very delicately on the (smooth) bottom of the body of water or pin it against some structure with thrusters

>some kind of tool is always nice, try a claw or a magnet or something to pick up stuff from the water :)

I think you can make paper with basically any plant. The quality and yield will vary though.

Isn't 4cm a bit too big? You will need more energy to move more iron on a longer distance.
When soldering, the varnish evaporate very quickly. That is a good solution if you can't remove it with sand paper. The electric contact will be better as well.

Well it takes a lot of math and science to come up with stuff. But once the math and science has been done it doesn't require as much.
But I put up a learning resources section with a little bit of science and math just in case.
Anyways, writing articles is time consuming and tedious.
I'm going to try to write an article every other day or so, but I was hoping people would chip in a little bit and polish the articles that already exist , like the wool article, or just copy and paste something.

Everything is carcinogenic, but some things more than others. Clearing a couple of minor projects of asbestos with regular PPE is no more carcinogenic than a couple of flights with an airline. If anything, it would probably be better if carpenters and masons did the job themselves with basic PPE the two or three times a year they encounter some asbestos, than to have designated people work with the stuff all day, every day for decades, even with extra super duper PPE.

there were 2 kinds of asbestos tiles.
Flexible "Cushion Vinyl" Tile which had a layer of loose asbestos paper underneath verry dangerous because they contain 95% loose asbestos.

and hard Tiles where the asbestos bound is inside the PVC layer and these are not that dangerous if they are not broken.

Plumber here, can confirm new ones are 1-2" taller. It looks like you have flexible copper connectors so you should be fine.
Dont fuck with dielectric unions unless you are getting it inspected (which you should also not do).
Make sure if yours is a "shorty" (short one) you get the same size

Seems like a dielectric union would be about the same as any other, are they less reliable?

He is just trying to drum up business. He wants to get a call in a few years about pressure loss on the hot water side. He'll come in, clean up the pipe, swap the unions, and charge you $600. He also probably does not have a license so he doesn't want people to get their shit inspected as that will cause trouble.

Hey /diy/, anyone have experience with outsourcing small CNC jobs to Chinese machine shops? I have a couple knife designs drawn up in CAD that I’d like to get machined as a personal project and I’m trying to figure out the best way to go about it[spoiler][/spoiler]. There’s a couple websites that offer instant quotes for very small runs from Chinese factories, but I’m also wondering if it would be simpler to put in a sample request through Alibaba or something.

I mean if the feed rate is too fast the sensors start kicking pieces into the scrap bin. Completely oversold on the production capacity. We assumed that meant producing good parts. Meanwhile our lead time in this department grew from 4-6 weeks to 6-8 weeks in the last couple years, despite auto business slowing down.

Ffs we've got old American cam drive machines from the 40s that work faster and better, however they only do simple shapes.

That and nice tight tolerances are nice. No reason to settle for the bare minimum. That's how you get crappy products.

In another 10 years people will just have their own CNC machine make the part for them. Hell as of now you can get a HBF mill for 400 bucks and then a CNC kit for that all for less than 800 bucks.
